On average, 50% of individuals suffering an ACL injury will develop radiographic osteoarthritis (OA) 10 to 20 years after injury. Unfortunately, ACL reconstruction does not prevent risk of future OA.\n\nInterleukin-1 (IL-1) levels in the human knee joint increase transiently after an ACL injury. In animal experiments, if interleukin-1 levels are increased in the joint, this alone causes arthritis to occur. Interleukin-1 receptor antagonist (IL-1Ra) is a naturally occurring inhibitor of IL-1. However, in ACL injuries the balance of these two proteins is disturbed transiently after injury, with the effects of IL-1 dominating this balance. In a large animal model of ACL injury, injection of IL-1Ra into the knee joint after ACL injury significantly decreased the amount of arthritis that was later observed. Thus, the investigators hypothesize that early injection of IL-1 inhibitor (IL-1Ra) into the knee joint of patients suffering recent ACL injury will decrease the incidence of cartilage damage later in life.\n\nAfter appropriate IRB approval, a total of 32 active patients will be randomized into one of two treatment groups. Group 1 will receive removal of the knee joint fluid (aspiration of hemarthrosis) using a needle and syringe within 1 to 2 weeks of injury. Following aspiration of the knee joint, an injection of 5 milliliters (mls) of sterile saline (as a placebo control) will be administered. In addition, a second knee aspiration procedure and an injection of 5mls of sterile saline into the injured knee joint will be performed at 3 to 5 days after the initial injection. Group 2 will receive aspiration of the knee hemarthrosis as described in group 1 as well as intra-articular administration of 150mg (\\~5mls) of anakinra (rhIL-1Ra) within 1 to 2 weeks of ACL injury. In addition, a second knee aspiration and intra-articular administration of 150mg (\\~5mls) of anakinra (rhIL-1Ra) will be performed at 3 to 5 days after the initial injection. Thus, all patients in this randomized placebo-controlled trial will undergo two injection procedures prior to surgery.\n\nInvestigators will analyze subjects self-reported function and pain scores as well as urinary levels of cartilage breakdown products over time. Additionally, MRI studies will be used to compare MRI findings among patients in these 2 treatment groups. Urine samples will be obtain prior to surgery, at the time of surgery and at multiple time points after surgery (3, 6, 9, 12 and 24 months after surgery). Subjective outcome measure assessments (surveys) will be completed by participants prior to surgery and then again at 6, 9, 12 and 24 months post-operatively.

The new scanner may be useful to diagnose conditions affecting tissues such as ligaments, tendons and cartilage more accurately, potentially improving the quality of care by the NHS. To develop such protocols and to test the clinical capabilities of the scanner, it is necessary to evaluate the scans of healthy volunteers before recruiting patient participants.\n\nConventional MRI scans are unable to detect the signal from tissues such as ligaments, tendons, cartilage and cortical bone, which contain highly aligned collagen fibres and the signal decays too quickly to be captured. These tissues appear black and are only seen because of the surrounding brighter tissues. If a bright region appears, it can be a sign of an injury or disease, but it can also appear due to the Magic Angle artefacts, when the collagen fibres are at a specific angle to the main magnetic field of the MR scanner. This anomaly can make assessment of these tissues difficult. Currently the diagnostic gold standard is arthroscopy, though it is mostly undertaken therapeutically.\n\nThe method harnesses this inherent tissue property to gain information about these collagen-rich tissues in joints. Using Magic Angle Direction Imaging (MADI) it is possible to obtain detailed information about the collagen fibre structures, and this is not available using conventional MRI. MADI could be important for planning surgery, developing new tissue implants, and monitoring outcome measures.\n\nIn both standard cylindrical scanner and the conventional open scanner, it is impossible to move the magnet, nor the patient, in the required manner. This motivated the development of a novel prototype MA scanner that can move around the patient.\n\nThe aim of this study is to evaluate the ability to routinely perform in-vivo Magic Angle-MRI of collagen structures in joints based on the magic angle principle, and to assess the ability to use qualitative and quantitative assessment of the Magic Angle-MR images to distinguish between the pathologies of the soft structures imaged.",[27,360],"Meniscus Tear",[362,363,364,365,366,337,367,368,369,370,371],"magic angle","musculoskeletal","low field","magnetic resonance imaging (MRI)","knee","degenerative meniscus","patellar tendon","magic angle directional imaging (MADI)","short T2","collagen fibre orientation","2026-01-16",{"date":341,"type":41},{"date":375,"type":41},"2025-01-29",{"date":377,"type":21},"2027-06-30",{"name":379,"class":48},"Imperial College London",2,{"id":382,"slug":383,"hasResults":12,"nctId":384,"briefTitle":385,"officialTitle":386,"acronym":4,"eligibilityCriteria":387,"healthyVolunteers":163,"sex":16,"minAge":388,"maxAge":142,"enrollmentInfo":389,"targetDuration":4,"studyType":22,"phases":390,"briefSummary":391,"conditions":392,"keywords":4,"overallStatus":37,"whyStopped":4,"lastUpdateSubmitDate":393,"lastUpdatePostDateStruct":394,"startDateStruct":396,"completionDateStruct":397,"leadSponsor":399,"locationsCount":49},"100618551","investigation-of-the-effects-of-proprioceptive-exercises-after-anterior-cruciate-ligament-surgery-100618551","NCT07333092","Investigation of the Effects of Proprioceptive Exercises After Anterior Cruciate Ligament Surgery","Investigation of the Effects of Proprioceptive Exercises on Balance, Kinesiophobia, and Functionality After Anterior Cruciate Ligament Surgery: A Randomized Controlled Trial","Inclusion Criteria\n\n* Being between 20-40 years of age\n* Having undergone anterior cruciate ligament (ACL) surgery\n* Being in the 2nd week of rehabilitation after ACL surgery\n\nExclusion Criteria\n\n* Having a concomitant meniscus injury\n* Having a concomitant medial collateral ligament injury\n* Being in the 1st week of rehabilitation after ACL surgery","20 Years",{"count":276,"type":21},[24],"The aim of this study is to investigate the effects of proprioceptive exercises on balance, kinesiophobia, and functionality after anterior cruciate ligament surgery.",[27,231],"2026-01-15",{"date":395,"type":41},"2026-01-20",{"date":393,"type":41},{"date":398,"type":21},"2026-08-20",{"name":400,"class":48},"Uskudar University",{"id":402,"slug":403,"hasResults":12,"nctId":404,"briefTitle":405,"officialTitle":405,"acronym":4,"eligibilityCriteria":406,"healthyVolunteers":163,"sex":16,"minAge":57,"maxAge":58,"enrollmentInfo":407,"targetDuration":4,"studyType":22,"phases":409,"briefSummary":410,"conditions":411,"keywords":412,"overallStatus":37,"whyStopped":4,"lastUpdateSubmitDate":417,"lastUpdatePostDateStruct":418,"startDateStruct":420,"completionDateStruct":422,"leadSponsor":424,"locationsCount":49},"100616485","effect-of-visual-guided-balance-training-on-knee-motor-function-and-biomechanical-characteristics-after-acl-reconstruction-100616485","NCT07306221","Effect of Visual-Guided Balance Training on Knee Motor Function and Biomechanical Characteristics After ACL Reconstruction","Inclusion criteria for patients:\n\n1.

Two rehabilitation strategies-low-load blood flow restriction (BFR) training and surface electromyography (sEMG) biofeedback-aim to enhance neuromuscular activation and strength while limiting joint load. However, comparative and combined evidence in pragmatic, multicenter settings remains limited.\n\nAMIRACL is a multicenter, prospective, randomized, controlled, parallel-group trial with four arms enrolling 200 adults (18-35 years) undergoing a first-time ACL reconstruction. Participants are randomized with center stratification; outcome assessors are blinded to allocation. The four groups are: (1) standard rehabilitation; (2) standard + early BFR; (3) standard + early sEMG biofeedback; and (4) standard + combined BFR and sEMG biofeedback. Interventions begin about 2 weeks postoperatively, are delivered over 6 weeks at three supervised sessions per week, and are integrated into contemporary ACL rehabilitation. BFR uses individualized, auto-regulated cuff pressure during low-load isometric and then dynamic exercises. sEMG biofeedback provides real-time visual and\u002For auditory feedback to optimize quadriceps recruitment during targeted tasks. The combined arm receives both modalities concurrently.\n\nThe primary objective is to compare quadriceps activation (sEMG) and maximal isometric knee extensor strength between groups at 3 and 6 months. Secondary objectives include return-to-sport readiness and patient-reported function (e.g., ACL-RSI, IKDC), broader knee outcomes (e.g., KOOS, Lysholm), adherence and adverse events across arms, and ACL re-injury (ipsilateral graft rupture or contralateral ACL injury) within 2 years. Longer-term patient-reported quality of life is explored up to 5 years.\n\nKey eligibility criteria include age 18-35 years, first ACL reconstruction, and preinjury sport participation; major exclusions include revision ACL surgery, concomitant multi-ligament repair, neuromuscular disorders, and contraindications to BFR or sEMG. The planned sample size is 200 (50 per arm), powered to detect a clinically meaningful between-group difference in quadriceps activation. Analyses will follow the intention-to-treat principle using mixed-effects models for repeated measures. The study is conducted under Good Clinical Practice and applicable Swiss regulations; all participants provide written informed consent.
